When coding with C language, typically we use head file to define global functions. If there is no necessary for one function to be called by other package, this function should be defined at implementation file(.cpp file) to avoid exposed to others.
In terms of the head files, it is necessary that using:

#ifndef __NAME_H__
#define __NAME_H__
...
#endif //__NAME_H__

Using this syntax to avoid the variables are re-defined when multiple .cpp files include a same .h file.
